Overbooking, rate-parity, and comp gates — stop oversold rooms, off-parity rates, and over-limit comps before a booking confirms.
For: Hotels, restaurants, OTAs, booking platforms
Blocks a booking that would oversell the room-type inventory.
Blocks published-rate overrides that breach a parity agreement.
Holds comps or refunds above the folio limit for a manager approval key.

Fork it, change the thresholds to match your environment, and deploy in shadow mode first — it defaults to listen-only so nothing in your live pipeline changes.
Follow the install path for this surface, then paste the forked YAML as your policy config.
This recipe is one step in a path. The same five steps apply to every recipe in the exchange.
Run the policy against a realistic action in the browser. Push it past what the rules allow and watch the verdict come back. No account.
See exactly what was decided and why: the rule that fired, the evidence it read, the policy version in force, and an Ed25519 signature you can verify yourself.
Measure what the policy would have caught on your own traffic without touching the live path. Every recipe defaults to shadow, so the first deployment carries no execution risk.
Point the same policy at the system where the action actually originates — a checkout, an ERP posting, a Zap, an agent's tool call.
Publish the proof: a public verification link, an embeddable badge, a PR comment, or an anonymized shadow-mode finding. This is how the next person discovers Decionis.
